a Development of the cerebellum appears normal. b Both hemispheres are fused up to the gyrus centralis (arrow) with presence of polymicrogyria. c Fusion of the anterior brain is encircled. Bulbus olfactorius is bilaterally absent (arrows) while the chiasma opticum is normal (dashed arrow). d Sequential coronal sections of the brain demonstrate the incomplete separation common to semilobar HPE. Inter-hemispheric fissure is invisible in the anterior brain (region encircled). The ventral horns of the lateral ventricle are absent, as well as the genu of the corpus callosum
